A climbing tree stand apparatus provides upper and lower platforms that are independently movable up the tree by the hunter alternatively sitting and standing on one or the other of the platforms. In order to adjust the angular position of a selected platform relative to the tree, an easily accessible adjustable anchor point is provided. This anchor point enables a cable associated with each platform to be lengthened or shortened in order to maintain the orientation of the platforms in a nearly horizontal position.

1. Field of the Invention
The present invention relates to elevated hunting platforms, particularly tree climbing devices such as those that are commonly employed by deer hunters. More particularly, the present invention relates to an improved climbing tree stand having upper and lower platforms, either or both having an adjustment system that enables a user to quickly and safely adjust the position of either or both of the platforms relative to the tree being climbed. The present invention enables a hunter to always maintain his or her tree stand climbing platforms in as close to a horizontal position as possible, during climbing and even with changes in tree diameter due to natural tree taper.
2. General Background of the Invention
Hunters commonly employ a climbing tree stand when hunting certain game animals such as white tailed deer, mule deer, hogs, elk, and the like. These climbing tree stands enable a hunter to hunt from a position that is 10–40 feet above the ground to hopefully avoid detection by the game animal. Game animals such as deer have a very keen sense of smell. Deer also have very good eyesight. Hunting from an elevated position can assist the hunter when hunting such game animals.
Several climbing tree stands are commercially available. Some of these designs have been patented. One of the most popular designs is sold by Ol' Man Tree Stands, Inc. of Hattiesburg, Miss. One of the Ol' Man designs is shown and described in U.S. Pat. No. 5,234,076 issued to Louk and entitled “Tree Stand”. An improvement to the basic '076 patent can be seen in a later U.S. Pat. No. 5,921,348 wherein the tree stand converts between selected positions that are suited to either bow hunting or rifle hunting.
The Louk U.S. Pat. Nos. 5,234,076 and 5,921,348 each employ flexible cables that extend about a tree during use and which have end portions that attach to upper and lower platform or frame sections of the stand. In the Louk '076 and '348 patents, the ends of the cables have eyelets that are contained within hollow bar members of the frame sections. Each of the cable eyelets is locked to a selected position with locking pins. The locking pins pass through holes in the hollow bar members of the frame and then through the cable eyelets. The pins thus affix the length of the cable at a selected position, depending upon the diameter of the tree being climbed. Adjustment while climbing is difficult or impossible because a hunter must manipulate three items simultaneously: the platform, the cable, and the locking pin. Any one of these can become unsecured during an attempted adjustment.
Some climbing stands employ rigid metal straps that extend around the tree such as those shown and described in the Amacker U.S. Pat. Nos. 5,090,504 and 5,316,104.
API Outdoors of Tallulah, La. manufactures and sells a tree stand that uses a flexible chain that extends about the tree to secure each platform. Otherwise, locking pins like the Louk devices present the same problem for any adjustment. The Yerger U.S. Pat. No. 6,082,492 discloses a safety belt for a climbing tree stand that includes a chain. Another Yerger patent 6,206,138 uses a chain as part of the climbing cable mechanism.
Many commercially available tree stands are sold by Cabela's, Inc. of Sidney Nebr. These various tree stand designs can be seen at the Cabela's website (www.cabellas.com). Bass Pro Shops also sells numerous climbing tree stand designs. The various climbing tree stands that are sold by Bass Pro Shops can be seen at their website (www.basspro-shops.com).
One of the problems that has long plagued the art relates to the adjustment of a climbing tree stand relative to the tree selected. When a hunter selects a particular area for a hunt, there may be only a few tall straight trees that are suitable for the attachment of a climbing tree stand. A hunter typically does not have a wide range of selections as to the diameter of the tree if a particular spot is to be hunted. The cable must be adjusted before the hunter begins to ascend the tree for the hunt. Often, the hunter is placing the stand on the tree in total darkness. This is quite common with early morning hunts because the hunter wants to be in position before daylight.
Trees are typically tapered, having a wider base and a narrow top. This presents a problem to the hunter that is using a tree climbing stand employing cables. As the hunter climbs the tree, the position of the cables relative to the stand platform frame portions remains fixed, causing the inclination of the tree stand platforms relative to the tree to change with changing tree taper. Ideally, the platforms are horizontal and form a right angle (90°) with the tree. When the platform angle is not at or near ninety degrees, the hunter is basically standing or sitting on an inclined rather than horizontal surface. Typically, as the tree narrows, the climbing platforms form greater and greater obtuse angles with that portion of the tree that extends above the platforms.
Prior art tree stands use locking pins or bolts to lock the cable to the stand. These locking cables are virtually impossible to adjust during climbing. To remove one of the locking pins creates a potentially disastrous situation wherein the user could drop the locking pin, rendering the stand inoperable and trapping the hunter twenty or thirty feet above ground level. Further, the hunter is at risk of falling because one hand must support a portion of the platform that is not supporting the hunter while the other hand attempts to make the adjustment. Few safe hunters ever attempt such an adjustment during climbing.
A tree stand platform apparatus includes one or two platforms that can be attached to a tree during use. When two platforms are used, the apparatus provides a climbing tree stand that enables a hunter to climb a tree with the apparatus and assume a position that is elevated for hunting. The apparatus includes a first platform with foot attachments for enabling a connection to be made between the first platform and a user's feet. A second platform is positioned above the first platform during use when climbing a tree. Each platform has a flexible cable that enables connection to the tree being climbed, wherein the cable has two free ends, one end attached to the left side of a platform, the other attached to the right side of a platform. The cable extends about a tree being climbed during use relative to the platform to which the cable is attached. An adjustment enables a user to adjust the length of the cable that extends from the platform to the tree, the adjustment being free of any separate locking pin. The adjustment enables a user to adjust the length of the cable that extends from the platform to the tree and can include at least one knot tied to the cable at a selected position that is spaced away from the tree, the knot providing a stop to limit the length of the cable that extends from the platform to the tree. The present invention also provides an improved method of climbing a tree with a climbing tree stand wherein a user can easily adjust the position of the tree stand platforms relative to the tree without requiring manipulation of: 1) the platform; 2) the cable; 3) a separate locking member.
For a further understanding of the nature, objects, and advantages of the present invention, reference should be had to the following detailed description, read in conjunction with the following drawings, wherein like reference numerals denote like elements and wherein:
Climbing is accomplished by alternatively locking the upper 11 or lower 12 platform to the tree by engaging the tree with a central portion 24 of cable 22 and simultaneously locking or engaging a blade 16, 34 or another contact point provided on each of the platforms 11, 12 into the tree. That engaged position of the lower platform can be seen in
In general, this concept of using upper and lower platforms having cables that encircle a tree and having blades, teeth or other contact point(s) that engage the tree is well known in the art. For example, climbing tree stands that feature upper and lower platforms can be seen in the prior Amacker U.S. Pat. Nos. 5,316,104 and 5,090,504 as well as the prior Louk U.S. Pat. Nos. 5,234,076 and 5,921,348, all of which are hereby incorporated herein by reference.
One of the problems that faces a hunter during the climbing of a tree is that of proper platform position relative to the tree. As shown in
The present invention provides a solution to this problem by enabling the hunter to quickly and easily adjust the length of the cable 22 that encircles the tree 14 and therefore insure at all times that the platform 11 or 12 will be generally horizontally positioned and forming an angle of about 90 degrees with respect to the tree 14 being climbed.
The lower platform 12 provides a frame 15 having decking or flooring 17 that enables a hunter to stand upon the lower platform 12. The flooring 17 can be expanded metal, transverse bars or the like. A blade 16 or blades or other contact point are provided on the frame 15 as shown in
Each of the frames 11 and 12 provides left and right upwardly extending struts 20. These struts 20 can be rigidly attached to the remaining portion of the frame 15, 31 by welding or can be pivotally attached such as those shown in the Louk U.S. Pat. No. 5,234,076, incorporated herein by reference. Each of the upwardly extending struts 20 provides an eyelet 21 through which cable 22 extends. The cable 22 can provide a flexible cover 23 to prevent abrasion and chaffing for that portion of the cable 22 that extends through the eyelets 21 and around the tree 14. Cable 22 can be of a rope material (eg. Kevlar®, Spectra®).
Cable 22 provides a first end portion 24, a second end portion 25 and a central portion 26. The central portion 26 extends from the platforms 11, 12 around the back of the tree 14 opposite the hunter 13 as shown in
An adjustable anchor point 28 is provided at second end portion 25 of cable 22. This second end portion 25 and the adjustable anchor point 28 enables a hunter 13 to change the length of the cable 22 that extends from first end portion 24 and anchor point 27 about the tree 14 and then to anchor point 28. The anchor points 27, 28 are preferably provided at the outer end portions 30, 33, of the platforms 12, 11. The frame 15 thus provides an inner end 29 and an outer end 30. The platform 31 provides an inner end 32 and an outer end 33. It should be understood that the cable 22, flexible cable cover 23, and anchor points 24, 25 can be of the same diameter, length, and material for upper platform 11 and lower platform 12.
An eyelet 37 is provided at anchor point 25 through which cable 22 extends as shown in
For purposes of illustration, the cable 22 as it passes through eyelet 37 can be described as having a number of sections 46–49. The section 46 in
In
In order to complete the adjustable anchor 28A, the cable 22 is passed through eyelet 37, routed over the front 30 portion of frame 15 of platform 12 as shown in FIG. 21. To further describe the adjustable anchor 28A, the cable 22 as it approaches and attaches to frame 15 is designated with various cable sections 86, 87, 88, 89. The cable section 86 as indicated by arrow 90 is that portion of the cable 22 that spans between the tree 14 and the eyelet 37. The cable section 87 is that portion of the cable that has passed through eyelet 37 and which extends under the front 30 portion of frame 15 of lower platform 12, as indicated by arrow 91 in
When a hunter wants to adjust the position of platform 12 relative to tree 14, the hunter simply lifts the platform 12 upwardly using the foot straps 18 in the case of the lower platform 12 while sitting on the upper platform 11. This releases tension on the cable 22. A hunter simply loosens the adjustable anchor 28A and then pulls on the cable section 89 in order to shorten the distance that the cable spans between tree 14 and eyelet 37. This procedure is reversed if the hunter wants to elongated the cable 22 that spans between tree 14 and eyelet 37. Because the cable section 88 passes under the cable section 87, the cable section 88 is tightly wedged against the eyelet 37 when the hunter stands upon platform 17 preventing any slippage of the adjustable anchor 28A.
An alternate embodiment of the apparatus of the present invention, designated generally by the numeral 10A is shown in
The side 59 can be provided with a hollow bore 63 that can be occupied by an end portion of cable 64 that is in the form of an eyelet 65. This enables the eyelet 65 to be secured at a selected position by placing a cotter pin or other locking pin member 66 through one of the adjustment holes 67 in the inclined member 59. The other inclined member 60 provides an open-ended bore 68 that can be occupied by an end portion of cable 64 that extends through the bore 68 and exits the bore 68 at position 69 shown in
In
A cleat can thus be used in place of the eyelet 21 and knot 38 shown in
Other cleats 73, 74 can be employed (as examples) to enable adjustment of the length of cable that extends from the selected platform 11 or 12 or frame 15. A single cleat could be attached to one side of a platform 11 or 12 as shown, or two cleats could be employed on opposing sides of a platform 11 or 12. If a single cleat is used on one side of a platform 11 or 12, the other side of the platform could be anchored to the frame without adjustability, or could be adjustably connected to the frame using a locking pin that attaches to an eyelet at the end of the rope or cable, like the cable and locking pin adjustment used in the Louk patents listed above, and shown in
In addition to the eyelet and cleats shown and described herein, other anchors, such as a winch, ratcheted winch, ratcheted sprocket, ratchet, grip, could be employed to attach the free end of a cable to the platform 11 or 12 or 50 when the user is able to grasp, manipulate, apply tension to or otherwise adjust the cable 22 or 64 and change its length according to the method of the present invention. If a chain is used in place of a cable 22 or 64, a cleat that grips the chain could be employed so that the hunter pulls on a free end of the chain that is exposed and the cleat (or winch, ratchet, grip) then is used to secure the chain once its position is correctly adjusted to ensure that the platform 11 or 12 or 50 is generally horizontally positioned.
The following is a list of suitable parts and materials for the various elements of the preferred embodiment of the present invention.
The foregoing embodiments are presented by way of example only; the scope of the present invention is to be limited only by the following claims.
